Which term describes the sharing of cultural elements across different societies?

The term that describes the sharing of cultural elements across different societies is diffusion. This process refers to the way in which cultural practices, beliefs, technologies, and other elements spread from one society to another. It often occurs through various means, including trade, migration, and communication, allowing different cultures to influence each other over time.

For example, diffusion can lead to the adoption of cultural items such as food, clothing, and language from one society into another, resulting in a blend of customs and practices. Understanding diffusion is crucial in anthropology as it highlights how cultures evolve and interact, leading to greater cultural complexity and diversity.
